(CNN)– The wife of Mississippi Gov. Haley Barbour says she is "horrified" that her husband is seriously considering a bid for the presidency.

In an interview with CNN affiliate WLOX in Biloxi, Marsha Barbour admitted the "overwhelming" task of a presidential run is something she may not quite be ready for.
"It's been a lot to be first lady of the state of Mississippi and this would be 50 times bigger," she said. "It's a huge sacrifice for a family to make."

The governor is still testing the waters of a potential bid for the 2012 Republican nomination and has made no formal announcement regarding his intentions.

But Marsha Barbour revealed she is wary of a 10-year commitment she believes would accompany a presidential run - and, presumably, two terms in office - during "the last part of our productive lives."

Despite her hesitation, Barbour said that the final decision is up to her husband.

"That's a commitment that I am praying about," she said.

"And if God and Haley decide to do it, I'm sure God will give me strength to be a good partner."

Barbour Communications Director Jim Dyke responded saying, "Mrs. Barbour said what we all know: There are unique demands posed by the daunting challenge of campaigning for and serving as president of the United States."
